2 Claims.

all of the juice from citrus fruits, such as oranges or lemons, anddeliver strained, potable juice free l0 of seeds, in a rapid andexpeditious manner.

Another object of my invention is to provide a fruit juice extractor ofthe type in which the juice is expressed from the fruit by means of aVreciprocating pressing member having means for l5 bringing the pressingmember rapidly into engagement with the fruit.

Other and further objects of my invention will appear from the followingdescription.

In the accompanying drawing which forms part of the instant specicationand which is to be read. in conjunction therewith, and in which likereference numerals are used to indicate like parts in the various views,Y

Fig. 1 is a top plan view of a fruit juice extractor showing oneembodiment of my invention.

In general, my invention contemplates the pro- L vision of a pressingmember in the form of a cup adapted to coact with a straining member,against which the fruit is to be pressed, of similar form.

The pressing member is carried by a rack adapted to reciprocate in astandard which carries the straining member. A pinion operated by alever engages the rack, the arrangement being such that the lever andthe pinion. and rack produce suicient mechanical advantage to exertsufficient pressing force to express substantially all of the juice froma half of a citrus fruit, as for example, an orange. The rack is formedonly on the upper portion of the reciprocating member,

the lower portion thereof being formed free of teeth. Spring means areprovided for urging the reciprocating member which carries the upperpressing member to its uppermost position, as shown in dotted line inFig. 3.

More particularly, refering now to the drawing, a standard I is providedwith a base 2. The

standard and base may be of any suitable con- (Cl. 10o- 4. 2)

figuration, preferably in the-shape of an `ornamental design. Thestandard` is provided wit-I1 a vertical bore 3 adapted to house aspring4 and a reciprocating member 5. ATrie upper portion of thereciprocating member is provided with rack 5 teeth 6 and carries abracket-like member ll to which the upper presser member 8 is secured bymeans of a screw 9. The socket for the upper pressing member ismadehexagonal in shape as is the upper portion I0 of the member 8. Thisl@ prevents relative rotation of the pressing memberv 8 and the bracketmembe:` l, reducing the tendency of the screw 9 to become loose duringoperation. The standard I is also provided with a U-shaped bracket Il,adapted to support a juiceV u receiving cup I2. The juice receiving cupI2 in' turn supports the combined male pressing mem# ber and thestrainer I3, which is provided with straining slots I4 and a pluralityof annular steps I5. The juice receiving cup I2 is provided with 20 lugsI6 adapted to fit inY corresponding holesl formed in the bracket I I.

Journaled in standard I transversely thereof is a shaft Il having an endthereof formed with or carrying secured thereto, a pinion I8 adapted 25to engage the rack teeth '6. The shaft I1 is se' cured in the standardby means of a washer 9 and a cotter pin 20. Secured to the shaft is anoperating lever 2| adapted to rotate the shaft and hence the pinion I8.430

The lower end of the reciprocating member 5 is formed with a lug 22. Ascrew 23 extends through the standard I and projects into the verticalbore 3 a suflicient distance to engage the lug 22. The juice receivingmember I2 is pro- 36 vided with a juice drainage spout 2d under which areceptacle such as a glass is adapted to be positioned to receive thestrained expressed juice.

As the operating lever 2i is lifted the reciprocating member will beforced to move upwardly 4o under the influence of the action of thepinion I8 upon the rack 6. When the bottommost tooth of the'rack leavesthe pinion, the spring Ill will cause the reciprocating member to moveupwardly in the position shown in Fig. 3. The pinion i5 being disengagedfrom the rack will rotate freely, and the Weight of the operating member2| is such that it will assume the dotted line position shown in Fig. 2.

With the parts in the dotted line position, that 50 is, with the femalepressing member 8 in the position shown in Fig. 3, and the operatinglever .2| shown in the position of Flg.2, the fruit juice extractor isin position to receive fruit fromwhich the juice is to be expressed. 55

A piece of citrus fruit such as, for example, an orange, is cut in halfand a half fruit with the cut side downwardly is placed over thecombined male pressing member and strainer. The operator then pressesupon bracket l and moves it carrying the female pressing member 8downwardly against the action of the spring 4. Slightly before thefemale pressing member 8 engages the rind of the fruit to be pressed thebottommost rack tooth will engage a tooth of the pinion I8. 'I'heoperating lever 2i will rotate counterclockwise, as viewed in Fig. 2.The downward motion of the reciprocating member 5 is continued againstthe action of the spring until the female pressing member 8 engages therind of the fruit to be pressed. At this time the operator will graspthe operating lever 2i with the disengaged hand and continue thecounterclockwise rotation thereof, forcing the reciprocating member 5downwardly through the mechanical advantage of the leverage of theoperating handle, and the mechanical advantage of the rack and pinion.The bringing of the pressing members 8f and I3 together squeezes thefruit, expressing the juice therefrom. The expressed juice will flow bygravity into the juice receiving cup I2 throughthe straining slots Iland out of the juice funnel Minto such juice receptacle as is provided.After the juice has been expressed from the fruit the operating handleis operated clockwise, as viewed in Fig. 2, raising the recipro catingmember 5 and its associated bracket 'I and pressing member 8. Thismovement is continued until the bottom-most tooth of the rack disengagesthe pinion, after which the spring 4 continues the upward movement. Therind may be then readily removed and the operation repeated.

After the device has .been used to express the juice from several piecesof fruit the juice receiving cup will contain considerable seeds, heavypieces of pulp and the like. The juice receiving member I2 can bereadily removed together with the combined straining and pressing memberI3 and readily cleaned.

It will be observed that I have accomplished the objects of myinvention. I have provided a simple juice extracting device which willrapidly express juice from citrus fruit in strained condition. Thedevice admits of easy sanitation and cleaning, and is compact so that itmay be easily stored in a cupboard at the home or occupy small s.,

space onV a soda fountain or bar.

It will be understood that certain features and sub-combinations are ofutility and may be employed without reference to other features andsub-combinations. This is contemplated by and is within the scope of myclaims. It is further obvious that various changes may be made indetails within the scope of my claims without departing from the spiritof my invention. It is, therefore, to be understood that my invention isnot to be limited to the speciilc details shown and described.

Having thus described my invention, what I claim is:

1. In a fruit juice extractor, a base having a standard, a bore in saidstandard, a rack positioned in said bore for reciprocation therein, apinion journaled in said standard having teeth engaging said rack, anoperating lever for said pinion to reciprocate said rack, said standargformed with a substantially semi-circular flang a juice receiving cupadapted to rest upon said flange, said standard being formed with a luprojecting above said flange and toward sai juice receiving cup, saidcup and said flange being formed with co-operating means adapted toposition said cup upon said ilange in a predetermined position, meansformed up'on said cup for co-action with said lug when said cup is insaid predetermined position for removably positioning said cup upon saidflange, and coacting pressing members supported by said cup and saidrack respectively, for expressing juice from fruit positionedtherebetween.

2. In a fruit juice extractor, a standard, said standard being formedwith a substantially semicircular flange adjacent the upper end thereof,a juice receiving cup adapted to be positioned on said ange, said cupand said flange beingv formed with co-operating means adapted to locatesaid cup in' a predetermined position, said means including a projectionon one member, said projection co-acting with the flange and juicereceiving member to maintain the juicereceiving member in predeterminedrelation with said flange, a pair of co-operating pressing members, oneof said pressing members being positioned in said cup, and means foroperating the other of said pressing members to express juice from fruitplaced therebetween.
